Hey All - thanks again for all of the responses. I have since realized that my preliminary assumptions and calculations may be incorrect. Can someone check my math here and let me know if I'm wrong?
My previous math of the tongue weight was based on using a 15% of GVWR assumption. My understanding is that you don't necessarily need 15% of tongue weight to prevent sway. My new understanding is that you can have as little as 10% tongue weight to keep it from swaying (especially since I'm planning on using a WDH with anti-sway built in).
New Math (Keeping the Same trailer, but changing some assumptions):
The Trailer is advertised as a Unloaded weight of 4,180 - I think it's safe to add about 320 extra pounds once the propane is added for a true UVW of 4,500 I would then add 1k for a 4 wheeler, 500 lbs for water, and 1k lbs for extra gear that we would haul with us. That gives us a normal operating weight of 7k lbs, take 10% of that gives us 700 lbs plus 100 lbs for the weight distributing hitch gives us 800 lbs plus family weight of 575-600lbs gives us realistic cargo usage of 1,400 - going back to our Tahoe's GVWR calculation is that we have 7,300lbs GVWR minus curb weight of 5,900 gives us 1,400 cargo capacity. Now that means that nearly fully loaded we will be at capacity. If we aren't towing with water in the tanks (I don't think we really ever will) that leaves us under the maximum.
Now I'm thinking it's definitely do-able. And hey if it isn't I guess I'll just upgrade to a truck. Can anyone spot check my math and reasoning?
